JOURNAL-BOX LUBRICANT DEVICE.

' To all whom it may concern:

Be it known that I, RICHARD Tonrm'rz,

--cant devices for'journals in which'the journal-box is provided in itsbottom with an oil chamber from which .theoil, or other lubricatingliquid is carried upward to the journal. i V

Theobjects of my invention, among other things, are to simplify andimprove the construction of the lubricatingblock so as to increase thepower of resistancein the block and to prevent any dirt or foreignmaterial in the oil chamber from passingup to the journal, and furtherto enable the oil or lubricant to be fed to the journal so that thebearing is continuously supplied with sufficient oil during therevolutions of the journal.

In the accompanying drawings, Figure 1 1s a longitudinal sectionalelevation of a journalb0X showing my improvement. Fig.

2 is a cross sectional view taken on the'line 22 of Fig. 1 looking inthe direction of the arrow. Fig. 8 is an enlarged perspective View of myimproved lubricating block. Fig. 4 is a horizontal cross sectional viewof the block shown in Fig. 3. Fig. 5 is an enlarged vertical sectionalview'taken on the line 5-5 of Fig. .4. Fig. 6 is an enlarged detailcross sectional viewof amodified form of construction for 'thelubricating block.

Similar numerals refer to similar parts throughout the several figures.

In the drawings 7 represents the journalboX having a bearing plateSsupporting the journal 9. The journal-box? is provided with a cap 10having the upper bearing plate 11. 1 Below the journal-boX'Y, is asuitably formed oil chamber 12 into which oil or other lubricatingliquid may be poured through suitable openings 13, located at the endsof the journal-box 7, as shown in Fig. 1.

The journal-box 7 with the bearing plate 8 have. a suitable opening,orslot, 14 formed therein, as shown in Fig. 1, through which 5 1 nyimproved lubricating block 15 projects Specification of Letters Patent.

to contact with the journal 9, The block 15 is preferably mounted on acurved spring 16,

'theends of whichrest on the bottom of the chamber 12, as shown in Fig.1, thereby causing the block 15 to bear closely against the journal 9.However, the block 15 may itself rest on the bottom of the chamber 12with the top surfacein' contact, or nearly so, with the journal 9.

Referring more particularly to Figs. 3 to 6 inclusive, the lubricatingblock 15 is preftop of the block 15. In practice I have found that thesechannels 18 are preferably not wlder than fifteen-one thousandths of anlIlCll, though I do not wish to limit myself to the size of thesevertical passages which permit the oil or ctherlubricating fluid topassupward through these channels to they ournal 9. The top surface ofthis block erably composed of a plurality of thin sheet is preferablyconcave, as shown in Fig. 2,

so that its entire top surface bears closely againstthe journal 9,though this is not essential. The outer edges of the sections '17aresoldered or welded along their sides,

as shown in Figs. 3 and 4, so thatmy improved blcck 15 is closed in onall four sides, having only the top and bottom surfaces open.

shown as composed of a series of sheet metal sections 20, both. endsbeing bent Ushaped,

and they are then assembled in vertical position and soldered or weldedtogether along the side edges at 21 as shown in this figure.

With the lubricating block 15in place in the journal-box 7 projectingthrough the j In Fig. 6, the lubricating block 15 is proved block is soconstructed as to drain the clean oil below the surface in the oilchamber.

It is obvious thatwith this form of construction as herein beforedescribed, the. block 15 has greater strength, stabilityanddurability'than others now in use for this purpose, and that thenarrewness ,of the vertical channels 18 effectively prevents .largerpieces of steel, emery, or other foreign matter, that generallyvaccumulate on I the top surface of the oil in chamber 12,

from rising to the top surface of the block 15 and cause injury to thebearing itself.

I realize that considerable variation may be made in the details ofconstruction.liere tofore shown and described and I do not wish to beunderstood as limiting my invention to the specific forms hereinillustrated.

Having nowdescribed my invention, what I claim as new and desire tosecure by Letters Patent is the following, viz:

1'. 'A lubricating block composed of plurality of flat sheet-metalsections lying so closely together as to form a series of narrow,transverse, capillary channels extending'from top to bottom, and closedon all four sides.
